Electric Circuit Analysis: DC and AC Fundamentals

Electric circuits are the fundamental building blocks of all modern technology, from simple appliances to complex computing systems. Understanding how current, voltage, and resistance interact is essential for any technical field. This course provides a robust foundation in circuit theory, enabling you to confidently apply core analytical techniques like nodal analysis and superposition to solve complex circuit problems and prepare for advanced topics in electronics and electrical engineering. What you'll learn: * Understand the core concepts of charge, current, voltage, resistance, and power, and apply Ohm's Law to basic circuits. * Master Kirchhoff's Voltage Law (KVL) and Current Law (KCL) for systematic analysis of complex networks. * Apply network theorems, including superposition, Thevenin, and Norton equivalents, to simplify intricate DC circuits. * Analyze circuits containing energy storage elements (inductors and capacitors) and understand transient responses. * Practice analyzing sinusoidal steady-state circuits using phasors and impedance concepts for alternating current (AC) systems. The course begins with defining fundamental electrical quantities and components before moving into systematic analysis techniques for DC circuits. We then transition to alternating current (AC) analysis, covering reactive components and complex impedance. This course is designed for absolute beginners with no prior knowledge of electrical engineering or physics. It is ideal for students, hobbyists, or anyone needing a strong theoretical foundation in circuit principles. Start building your foundational knowledge of electrical systems today.
